高三英语第一轮复习主要进行的是单词的积累和语法的全面掌握，在上课课文学习和课后阅读练习中不断巩固抓牢，为后面的做题演练大幅度提分打基础。高考频道整理高考英语常考词汇用法及高考英语语法，帮助大家分小节记忆。

so that 以便于;目的是为了。相当于in order that,引导目的状语从句。从句中常带有may/might;can/could;will/would/should等情态动词

①He got up early so that he might catch the first bus.他早起为的是赶上第一班车。

②I put on my glasses so that I could see more clearly.我戴上眼镜为的是看得清楚点。

③He spoke loud so that everyone could hear him.他大声说是为了让大家都能听到。

以上各句中的so that均可用in order that代替。

当so that从句的主语与主句主语一致时，常可简化为in order to或so as to 结构。

上面的①②句可转换为：

①He got up early in order to catch the first bus.

②I put on my glasses in order to see more clearly.

上面的③句不可简化。但：

He spoke loud so that he could be heard by everyone.可转换为：He spoke loud in order to be heard by everyone.
